Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.

We really want to use an eCrate to restomod an old GM car. Here's what we'd build

You hopefully saw the news today of GM's introduction of its Connect and Cruise eCrate motor and battery package, which effectively makes the Bolt's electric motor, battery pack and myriad other elements available to, ah, bolt into a different vehicle. It's the same concept as installing a gasoline-powered crate motor into a classic car, but with electricity and stuff.  This, of course, got us thinking about what we'd stuff the eCrate into. Before we got too ahead of ourselves, however, we discovered that the eCrate battery pack is literally the Bolt EV pack in not only capacity but size and shape. In other words, you need to have enough space in the vehicle to place and/or stuff roughly 60% of a Chevy Bolt's length. It's not a big car, but that's still an awful lot of real estate. There's a reason GM chose to simply plop the pack into the bed and cargo area of old full-size SUVs. Well that, and having a rear suspension beefy enough to handle about 1,000 pounds of batteries.  So after that buzz kill, we still wanted to peruse the GM back catalog for classics we'd love to see transformed into an electric restomod that might be able to swallow all that battery ... maybe ... possibly ... whatever, saws and blow torches exist for a reason.  1971 Buick Riviera Consumer Editor Jeremy Korzeniewski: If you’re going to build an electric conversion, why not do it with style? ThatÂ’s why IÂ’m choosing a 1971-1973 Buick Riviera. You know, the one with the big glass boat-tail rear end that ends in a pointy V. Being a rather large vehicle with a big sloping fastback shape, IÂ’m hoping thereÂ’s enough room in the trunk and back seat to pack in the requisite battery pack. That would likely require cutting away some of the metal bulkhead that supports the rear seatback, but not so much that a wee bit of structural bracing couldnÂ’t shore things up. The big 455-cubic-inch Buick V8 up front will obviously have to go. Remember, this was the 1970s, so despite all that displacement, the Riviera only had around 250 horsepower (depending on the year and the trim level). So the electric motorÂ’s 200 horsepower and 266 pound-feet of torque ought to work as an acceptable replacement.   1982 Chevrolet S10 Associate Editor Byron Hurd: OK, so the name "E-10" is already taken by a completely different truck, but let's not let labels get in the way of a fun idea.

More Corvette Stingray Factoids: Vanishing panel gaps and 26-mpg LT1

During January's Detroit Auto Show, we managed a longer than expected wandering tag-team interview with C7 Corvette chief engineering exec Tadge Juechter (pictured above), and LT1 engine boss Jordan Lee (pictured below). They are, quite honestly, two of the very nicest bigshot lads to ever walk the engineering corridors of an American manufacturer. Both are enthralled by what they're doing for a day job. So are we.
We've followed the pre-sale anticipation for the Chevrolet C7 Corvette Stingray like an Oreck vacuum yanking every speck of dirt from a well-trampled carpet. Everything is reportable and contains a grain of further knowledge about this dramatically important and cheered-for car, as it continues to be pressured into representing all that is superior about the American dream. The Corvette wears one heavy cloak.
So, most of what was talked about has been expertly reported already right here on Autoblog. But, looking through our notes again, both Jeuchter and Lee added facts to the buzzing mix.
